An Anonymous Girl by Greer Hendricks, Sarah Pekkanen

 It was so miserably slow at the beginning it almost made me DNF and I love a slow burn. Twist was pretty decent but resolution was just meh. Whole experience was meh.

 
Spoiler Dr. Shields tries to find the right girl to test her husband's fidelity (after he cheated before with a client). Once they both turn on Dr. Shields (she ends herself after she got his previous affair to - to protect his career as a psychologist) the 'anonymous girl' decides to blackmail him for money. Jessica (anonymous girl) found out she was a client because of a quote on a coffee mug in his office so not only is he a cheater, he's unethical... so him and Shields were really perfect for each other!
